Few filmmakers at work today can claim to have more visual flair than Nicolas Winding Refn. From his debut thriller Pusher to Drive, Only God Forgives and The Neon Demon, he has always served up a feast for the eyes.

Invariably his themes are downright dark and sleazy - with tech-noir soundscapes and cinematography enhancing the mood. Whether using source music or score, the Danish director is most accomplished when it comes to sonic dressing.

Nicolas has enjoyed a particularly fruitful relationship with composer Cliff Martinez. We'll hear plenty more about that during the course of the interview, as well as excepts of score from the movies on which they've collaborated.

Nicolas also gives us a fascinating insight into how he deploys music to induce a profound emotional response from his cast, and also reveals what he considers to be the Holy Grail of score.
